Hi @Bob1485
If Airbnb said they were responsible for collecting local lodging taxes, but didn’t, it might be an uphill battle to resolve this. Unfortunately, if a tax is required, but not collected on your previous bookings, you will still owe the tax (as you discovered). See another thread on this issue:
Getting Airbnb to Add a New Local Lodging Tax

Looks like you have been hosting for just over a year? We always suggest new Hosts keep their own spreadsheet of every reservation and breakdown all the taxes (sales & lodging) by jurisdiction in case it’s needed. This will help you verify if Airbnb is calculating taxes correctly and immediately spot if a specific tax is not being collected. This will enable you to avoid unpleasant surprises come tax time. Unfortunately, this might be an uphill battle for you with Airbnb. Other Hosts have connected with their local taxing authority and with Airbnb to determine what is required for this to be remedied properly.
Airbnb groups all taxes (sales tax/lodging tax) under the heading "Occupancy Taxes" in a reservation. You will have to do the math on your spreadsheet and breakdown sales tax and lodging tax for each jurisdiction that applies to determine if the amount is correct:

You can see what taxes are currently being withheld (but not the specific percentage breakdown) by going to:
- Listing
- Policies & Rules
- Laws & Regulations
- Taxes

In the mean time, I would suggest adding a custom tax to your listing, so at least the tax will be collected on reservations until Airbnb corrects this. It doesn’t matter if you have Instant Book, as it should appear correctly on any reservation. Be sure you monitor every reservation and use your spreadsheet. This will allow you to remove the custom tax once it has been corrected by Airbnb. Be aware that since it is a custom tax, you will be paid the tax and are responsible for then remitting it to the local tax authority; not Airbnb. This will require coordination so you are not taxing the guest twice for the local lodging taxes. I believe you need to have Pro Tools turned on (Account Settings) in order to add a custom tax.

After adding the custom tax, it should appear as "Property use taxes" on your reservations:

Let us know here how it goes as many other Hosts experiencing similar problems. It's not being discovered until tax time (year end) unfortunately.
